To all 'whom it may concern:A

Beit known that I, JOHN W.`TROEGER, 'of La Grange, county-of Cook, land State of Illinois, have invented certain new and useful -Improvements in Shingles, of Which the `following is a specification. g This invention has relation to shingles, and the object of my invention is to produce alight, .practical and durable substitute for the various kinds offshingles now in common capable of cheap production. v- 1 The composition roofing ordinarily used in shingles, 1n appearance, that it is generally objectionable for residences, and themethods of cutting the sheets into strips having.

oints, scallo s or tongues, is open to the ob- Jection that t e strips must be nailed to the roofboards at theedges where the nail-heads are exposed to the Weather causing them to The' action of .the rust causes the felt or fabric roofing to deteriorate around the nails allowing the water to leak through the roof and making it unserviceable My invention is a composition shingle whichis applied to the roof in the same manner as the well-known wooden shingle, producing the same shingle effect as to appearance, and has a pleasing natural color or'may be ainted as desired.

' he invention consists of the featuresof construction and combination of parts to be herein more fully described and particularly pointed outin the appended claims.

Referring-to the accompanying drawings,

` Figurel represents the shingle in perspective,

and. Fig. 2 is a cross -section of the saine,- show'ing the several layers in combinatiom Figs. 3 and 4 represent views of cross-sections of shingles'in which the coatings are applied in slightly different forms.' Fig. 5 s ows .the'shingle made with two layers of foundation fabrics; A

- screening or other roofiligfabrics, impreg-` Like letters refer to like parts. l" A The foundation of the shirligle may be felt; cloth, fibrous board, pe orated metal,

v nated or filled with a Water roofing compound. The sheet is cut into s ngles of 'convenient'sizes, and a layer or coating of plastic-weather-proof materialis applied to the upper face and, preferably, one ,to the under face. Thesecoating layers may be applied in various forms. The 'finest serviceable form is to apply a thinlayer of the coating to the upper side, which resists the acid often present in buildings, and a heavier layer to the upper face and to reinforce this layer with a second layer extending over about half its length, being thickest at the butt end,

Where it diminishes abruptly down to the first layer. '.As the shingle is 'waterproof through and through andas the thin end is not exposed to the Weather, it is not necessary to be heavily coated. The double layer of coating on the butt endA serves several useful purposes: 1.. `It greatly increases the durability of thel shingle whereit is ex- `B, and tapering slightly to the middle, M,

posed to the eroding effect of the Weather, f

withoutusing up unnecessary material; 2. It increases the rigidity of the shingle and hence its power to.| resist the curling effect ofthe sun, so thatl it lies snugly upon the course beneath and. remains so. 3. It strongly reinforces the shingle at the nailing line, which affords the nails or other fasteners a firmer and more-lasting hold on it.v The upper half of. theshingle being tapering in form, it

makes a level plane on which the next course lies snugly and at the sa'me time saves coat-- ing material where it serves no useful purpose; this is amatter of economy and makes the shingle comparatively lighter.- 4. The additional thickness of the butt end more clearly distinguishes the courses or layers on the roof and makes the resemblance to the familiar Wooden shingles more pronounced.

The upper layer of coating may also ,be alpplied as shown in Fig. 3, being thickest at t utt end, B, and-tapering graduallyand uni'-v formly to the tip end, A.

Fig. 4 shows a form in'which the plastic l coating is ap lied to both upper and lower faces in varia le thickness, beginning at the butt end, B, and tapering uniformly to the tip end, A. In Fig. 5 is shown across-section of ahingle @having a double layer -of foundation abric, j', held to ether by la cementing layer,

C. The coating ayers, cc and St, are applied in thes'ame mannerlas to the single ayer i fabric, as described in reference to Figs. 1, 2

and 3. The plastic coating may be applied lonly on the upper faceor on both the upper Itl may be uniform in thickness on the under face and of variable` and lower faces,7

thickness on 'theupper face or uniform on both faces, in accordance with the wishes of the maker. 'Any number of layers may be used in this manner, the object being to pro` --duce a ,shingle of special lthickness and porous baseer fabric impregnated With a strength.

These shingles are laid' in courses, one

labove the other, in the same manner as the common Wooden shingles leaving four or more inches of the butt end exposed to the Weather. They are fastened to the roofboards or sheathing with nails or staples, acrosstheJ middle ofthe shingle Where the succeedngcourse Will protect'the nails from the effects ofthe Weather.

Having thus described the invention, what I claim and Wish to secure by Letters Iatent 1s- 1.\The herein described shingle having a Waterproofing compound, a layer of Weatherproof coating a phed to both faces and the u per face rei orced with a second layer for about half its length, substantially as and for the purposes set forth.

- The herein described shingle having a Waterproofing compound, a layer of Weatherproof coating, of uniform thickness, Aapplied to the under face' and a layer of .variable ,thickness applied to the upper face, making the shingle Wedge-shaped, substantially as and for the purposes set forth. e

3. rI`he"herein described shingle having a multiple layer of f1l-crous fabric impregnated With a Waterproo g ,compound and cemented together and a coating of Weather-proof material, of variable thickness, ta ering from one end to the other, applied to t e u per and under faces, making the Shing e Wedge-shaped, substantially as and for the purposes set forth.
